4 Claims.

The object of this invention is to provide a positive locking means forthe flash mechanism of a register and for purposes of illustration wehave shown such a look as applied to the type of register disclosed inthe application of Albert S. Wheelbarger, Serial Number 236,094, filedNovember 28, 1927.

In the drawing- Fig. l is a side elevational view of part of such aregister showing our improved locking mechanism incorporated therein.

Fig. 2 is a side view of the opposite side from that shown in Fig. 1,and

Fig. 3 is a detail view of the flash setting cam and the lever directlycontrolled thereby.

There are a plurality of setting levers 1, only one of which is shown.Each of the levers 1 is connected to a gear 2 which drives a gear '7operatively connected to a gear 9 which drives a gear 10 secured to theindicating drum 11 which is provided with suitable characters or figuresto indicate the class of transaction or amount thereof.

The flash is mounted on the shaft 53 and consists of end plate 54 and aconventional end plate on the opposite side thereof, which end platesare connected by two plates 56 on which is written the words notregistered or similar indicia which indicates both to the front and tothe rear of the machine that the registration has not been made. As soonas the registration is made the flash is moved clockwise as viewed inFig. 2 so as to move the two plates 56 into the position shown in Fig.2. In this position the indicia on the flash is moved out of alignmentwith the sight openings in the front and rear of the casing 51.

The shaft 57 is provided with a plurality of levers 58 only one of whichis shown. Each of these levers 58 carries a roller 59 which engages theteeth of its corresponding gear 2 mounted on the shaft 60. Each lever 58is actuated so as to hold its roller 59 in engagement with the teeth ofthe gear 2 by means of a spring 61. An arm 62 is rotatably mounted onthe shaft 57, there being one such arm on each side of the machine,which arms are connected by a cross bar 64 lying immediately in front ofeach of the levers 58. Secured to one of the arms 62 is an arm 65connected to a spring 67 which in turn is secured to any fixed part ofthe machine. The spring 67 by pulling upwardly on the arm 65 holds thecross bar 64 in engagement with the levers 58. The arm 65 is providedwith a pin 63 which engages a bell crank lever 69 mounted on a pin '70in the right side wall of the frame. The bell crank lever 69 has anupwardly extending arm as clearly shown in Fig. 1 so as to engage withthe seat '71 or 72 in the plate 54 of the flash. These two seats areconnected by a sloping surface 73.

The machine is operated through a crank handle 74 connected to a gear'75 which drives a gear 76 on a shaft '77 which drives 9. Geneva gear'78 which drives a Geneva pinion '19 on a shaft 80 which Geneva pinion79 drives a gear 81 on a shaft 82. The Geneva. gear '78 and Genevapinion 79 are so constructed that the shafts 80 and 82 are rotated onlyduring the last part of the revolution of the crank handle '74 and thepinion and gear 81 make one complete revolution each time the machine iscompletely operated. The shaft 82 is provided with a cam 83 which has acut-away portion 84 forming a recess in which normally lies the lowerend of lever 85 pivoted on a rod 86. The upper end of the lever 85engages one arm of a bell crank lever 87 pivoted on a cross bar 88. Aspring 89 constantly tends to urge this lever in a counter-clockwisedirection as viewed in Fig. 1. The upper end of the bell crank lever 87is bent outwardly so as to extend through an aperture 90 in the casing.The upper end of the bell crank lever 87 carries a pin 91 which engagesbetween two arms 92 in the plate 54 of the flash.

In operation the respective levers 1 are moved so as to rotate itscorresponding drum to the desired position. As soon as anyone of theselevers 1 is moved, the teeth of its corresponding gear 2 will cause thelower end of one of the levers 58 to move outwardly or away from thesaid gear. This movement will move the cross bar 64 in acounter-clockwise direction as viewed in Fig. 2 or in a clockwisedirection as viewed in Fig. 1 so that the pin 68 carried by the lever 65will engage the bell crank lever 69 and rock the same clockwise asviewed in Fig. 1 so as to disengage the upper end 55 of the said lever69 from the seat 71 whereupon the spring 89 will rotate the bell cranklever 87 in an anti-clockwise direction and thereby rotate the flash ina clockwise direction as viewed in Fig. 1 or an anti-clockwise directionas viewed in Fig. 2 thereby moving the plates 56 so that the indiciathereon is in alignment with the sight openings 50 in which position theflash is stopped by the end 55 of the lever 69 engaging the seat '72.This shows that the amount set up has been indicated but it has not infact been registered for the registration will not take place until thecrank handle '74 has been operated, or if electrically operated, untilthe shaft 77 has been rotated one complete revolution. As soon as it isrotated the shaft 82 will likewise be rotated and the lever 85 will beactuated by the cam 83 so as to move the lever 87 into the positionshown in Fig. 1 and thereby rotating the flash so as to move the plates56 out of alignment with the sight openings 50. The seat '71 has thusbeen moved above the upper end of the lever 55 and the spring 93 movesthe lever 55 into a position to engage the seat '71.

In rapidly operating the machine, however, it has been found thatsometimes the spring 93 does not properly hold the end 55 of he lever 69in its proper seat. The principal object of this invention is to pr videa positive locking means so that the lever 69 cannot be displaced. Tothis end we have provided a square lug 94 on the lever 69 approximatelymidway between the fulcrum pin '70 and the extreme upper end thereof. Wehave also provided. a cam 95 which is clearly shown in Fig. l which camr'gidly secured to the shaft '77, which it will be remembered. makes onecomplete revolution upon each operation of the machine.- A push rod 96has a pin 97 and slot 98 connection with the side wall of the machine.The lower end of the push rod 96 rides on the periphery of the cam 95and the upper end 99 is adapted to engaa the lug 94 until the cam 95 haspractically corn eted its revolution, at which time ne cam point 180 haspassed beyond the lower extremity of the push rod 9L and spring 101pulls the push rod downwardly thereby disengaging the upper end 99thereof from the lug 94.

It will ther-iore be noted that whenever one 3 of the levers 1 is movedthe flash is instantly thrown to show that the machinehas not beenoperated, that is the registration has not been made. It has simply beenindicated. When the registration has been made, however, by the rotationof the shaft '77, the flash is moved to show that the registration hasbeen made and with the positive locking means which we have shown anddescribed it is impossible for the flash mechanism to be jarred so as toindicate that the registration has not been made when it Having nowdescribed our invention,

We claim:

1. In a register, a setting means a two position flash controlled bysaid setting means, a lever adapted to engage said flash in both of itspositions, means to lock said flash through said lever so that it cannotbe moved from non-obscuring position during actuation of the register,and means to unlock said flash when the register has completed aregistration so that the register can be adjusted to set up a succeedingregistration.

2. In a register, a flash having two seats thereon, a lever adapted toengage normally one of said seats, setting means whereby said lever maybe disengaged from the last mentioned seat, means toshift thereupon saidflash so as to bring the other of said seats into position to be engagedby said lever, operating means, means whereby the operating means whenbeing operated shift said flash so as to bring the normally engaged seatinto position to be engaged by said lever, and means to thereafterpositively lock lever against any movement until the operating means hascompleted its operation.

3. In a register, a flash having registered and non-registeredpositions, a setting means, a leverto hold said flash normally initsregistered position, means whereby said flash is shifted toitsnon-registered position when said setting means is operated, anoperating means, means to shift said flash to its registered positionsothat it will 7 ter, flash having a seat thereon correspondingto theoperated position of the flash, a lever engaging said seat, a lugcarried by said lever, and a slide adapted to be actuated by theoperation of said register and to engage said lug and holdsaid leveragainst displacement until the operating means forthe register hascompleted its operation.
